FileMaker 11 / 12 mixed client server environment ???
It appears based on my test environment that you cannot upgrade client workstations to FM 12 and have them access the currently in production FM 11 server. Can someone confirm this to be true? The reason why this would be advantageous is you could push out client installations remotely and verify all workstations have been successfully upgraded via reporting software before upgrading the server so this can be done in stages. It seems the only option is to upgrade all clients and servers in one fell swoop. Yes, I realize there is a new file format so I'm sure that's why this is necessary, but for larger deployments this could be a pain point. Thanks
This is not possible.
Unlike versions 7 through 11, Filemaker 12 uses a new file format that is not compatible with previous versions. All clients and server must be Version 12 or all clients and server must be a version in the 7 through 11 series...
